I would suggest getting a short piece of rail that would fit and drill out for sling stud and great choice for long range I shoot a stealth in 338 lapua also fairly new to long range have managed to ring my 2 foot gong at just over a mile and hope to break the 2 kilometer mark this summer I know the rifle can do it I need skills for reading the wind at those ranges but not complaining its the journey as I continue to be more proficient at longer ranges it is the best hobby I have ever had and always challenges you every time you go out.
